usually 110.00 a case of 4 gallons for KLOTZ!!! (lately)...The KLOTZ snowmobile oil mixes well with yamalube... DO NOT BUY SUPER TECHNIPLATE!!!!!! It WILL NOT MIX WITH REGULAR OIL!!!!! man will you have a disaster if you do!!!!! it kinda gels up like jello!!!!!!! Super Techniplate is premixed NEVER INJECTED!!!!! AS far as resetting/leaning out the oil pump,,,, I DON'T!!!! Because I would rather have too much oil than not enough.... YES synthetics can be mixed 100 to 1 while regular oil can go to 50 to 1.. BUT,,,,,,,,,AND HERE IS WHERE IT GETS TRICKY!!!!!!!!! SYNTHETIC OILS HAVE A SUPERIOR DETERGENT PACKAGE compared to MOST 2 stroke conventional oils... The detergent package actually keeps the exhaust valves cleaner,,,,, an over rich condition of KLOTZ, (like not resetting your pump) will help even better with keeping the valves clean and from sticking...... MOTOR OIL DOES NOT DIRTY UP THE VALVES..... The residuals from combustion are CARBON,WATER, besides all the rest co2 and oxides of nitrogen etc...etc...etc... The KLOTZ actually keeps the carbon deposits "gummy" (gummy is a bad word)... but...it keeps carbon from getting hard!!!! That in turn, keeps your valves cleaner,,,, NOW THERE IS A HUNDRED different theories and a thousnd different reasons WHY someones valves get dirtier than others,,, but SYNTHETIC OILS (any of them) Have FAR SUPERIOR detergent packages in them than YAMALUBE!!!!! BUT,,, THE ethers in MTBE DID actually help with carbon deposits..... WITHOUT GETTING INTO THERMAL DYNAMICS or todays Physics lesson,,,,,,, KLOTZ works well.... Gary Oles nosboy
